The final development at Erma is known as the EMP 36. This can be considered an intermediate model between the EMP and the MP38. Although many details of the mechanism were changed from the EMP, it retained Vollmer's telescoping main operating spring basically unchanged.

The EMP-35, or Erma Maschinen Pistole 1935, sometimes simply referred to as the MP-35, was a blowback-operated submachine gun that was used by Germany during World War II. It fired the 9 x 19 mm Luger/Parabellum cartridge, and had a magazine capacity of 25 or 30 rounds.

MP-35冲锋枪将弹匣插口换在了右侧，同时修改了各种细节设计，使得该枪无论是精度、射速还是可操控性都好了很多。 实际上，在二战初期很多德国士兵手里拿的是MP-35、MP-28以及 博格曼MP-34 （博格曼仿制的奥地利斯泰尔MP-34，后者为奥地利参考MP-28生产的）冲锋枪，因为当时MP-38（MP-40前身）的数量不多。 【图4：MP-35冲锋枪】 在MP-40之后还有一个MP-41，这款冲锋枪很少见。 MP-41就是给MP-40换用了木质枪托且取消了手枪式握把。 MP-41可以通 …

The Erma EMP, also called the Erma EMP 34 & Erma EMP 35 (not to be confused with the Bergmann MP 35/I‎) or the Erma MPE, is a German submachine gun, which was manufactured from 1931 to 1938 by Erfurter Maschinen- und Werkzeugfabrik Berthold Geipel GmbH (ERMA). The terms EMP and MPE stand for Erma-Maschinenpistole and Maschinenpistole-Erma.

The Erma EMP-35 (or EMP) was a blowback submachine gun designed by Heinrich Vollmer during the early 1930s. It was manufactured by Erma Werke and was extensively tested during the Spanish Civil War, where it was later mass produced on license chambered in 9mm Largo.

The Erma EMP-35 submachine gun was designed by German arms designer Heinrich Vollmer in the late 1920s and early 1930s. Manufacturing rights were sold to Erma in 1931. Erma produced various models called the EMP (Erma Maschinen Pistole) which differed in barrel length, sights, safety features, and accessories.

Erma EMP submachine gun is blowback operated, selective-fired weapon which fires from open bolt. It uses characteristic bolt system with telescoped tubular guide for return spring. The standard safety consisted of a hook-shaped notch in the receiver, which was used to engage and lock the bolt in cocked position.
